Absorb-&-Lock™ strips swell up to pull in high volumes of water. Absorbed water is “locked” inside, it won't run out when you pick up or dispose, even when fully saturated. Each strip could weigh up to 11 pounds & be 3” when fully saturated. The strips are ideal for tight spaces & once they expand will create a barrier to help prevent leaks from escaping and spreading. These are ideal for use around windows, doorways, sinks, basements or other water prone areas. Not Recommended for Foot Traffic.
